I want to select a record

SQL

ISNULL( MAX(CAST(RIGHT('012016031800001',15) AS VARCHAR(15))), 0) + 1

this gives an error like

The conversion of the varchar value

JavaScript

'012016031800001'

overflowed an int column.

What I have tried:

SQL

SELECT ISNULL( MAX(CAST(RIGHT('012016031800001',15) AS VARCHAR(15))), 0)+1

Well...yes.
The max value you can get in an INT is 2147483647
And you are trying to add one to:

C#

012016031800001
     2147483647

See the problem?
I'm not exactly sure why you are doing that: the VARCHAR cast is already unnecessary, and the ISNULL is also pretty redundant by that point.
This may be what you need:

SQL

SELECT MAX(CAST(RIGHT('012016031800001',15) AS BIGINT))+1

But...If you are trying to use this to generate unique IDs in advance, that's a bad idea!

you are trying to add a varchar value with an integer value
try this

SQL

DECLARE @MAXCODE varchar(15);
SELECT  @MAXCODE=ISNULL( MAX(CAST(RIGHT('012016031800001',15) AS VARCHAR(15))), 0) +'1'
PRINT @MAXCODE
print len( @maxcode)

SQL

DECLARE @MAXCODE varchar(16);
SELECT  @MAXCODE=ISNULL( MAX(CAST(RIGHT('012016031800001',15) AS VARCHAR(15))), 0) +'1'
PRINT @MAXCODE
print len( @maxcode)

The max data value of in is

2147483648

how to get the max value of int.

Select Power(cast(2 as varchar),(32) -1) as 'int max range'  from sys.types Where name = 'Int'

you can you BIGINT instead of Int

SELECT MAX(CAST(RIGHT('012016031800001',15) AS BIGINT))+1
